Buck Distributing Company was founded in 1946 by Wm Irwin Buck; he ran it with one truck, selling Valley Forge and Old Export beer.

In 1952 Mr. Buck picked up Miller Brewing products for Prince Georges County and three southern Maryland counties, Calvert, Charles, and St. Mary's. In 1971, Mr. Buck was given the rights to distribute Molson beers for the whole state.

In 1985 Mr. Buck's daughter, Betty, took over the operation of the company. In early 1986 Betty was named president; her father died later that same year. The company has continued to grow. In 1988 Buck Distributing added a fifth county to their territory, Anne Arundel, with the acquisition of Chesapeake Bay Distributing Company. Buck Distributing moved into a new warehouse in August of 2002. This new facility is designed to accommodate the company's growth as they continue to expand their portfolio. In the past 10 years Buck has added Yuengling, Spaten, Heavy Seas, Flying Dog, Yards and Port City Brewing Co. to their portfolio.

Buck Distributing now employs over 100 people, supplying fine products to their customers. As a result of their hard work and commitment to excellence, the company has been awarded the prestigious "Miller Masters" Award in 1986, 1987, and 1992 and the inaugural MillerCoors "Presidents Award" in 2009, 2010, 2012 and 2015.
